Local Environmental Conditions
River oak lines the bank, contributing some of the season's more persistent wind-borne pollen; this sits close to this spot. A canopy of eucalypt threaded with wattle, wattle chief among them for allergenic potency here; this sits not far from here. A park combining lawn grass and plane trees, both contributors to pollen here through the warmer months; this sits within the neighborhood.
The bank's river oak kicks off the pollen season ahead of the rest, climbing steadily from mid-winter into September. Eucalypt and wattle nearby take over the pollen calendar through late winter, building to its sharpest point across August and September. Grass pollen builds through spring and peaks in November, with the season extending well into summer before finally winding down in February.

How often is the Rose Bay pollen forecast updated?

Does pollen in Rose Bay come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Rose Bay based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Rose Bay, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
